Vega packed 16bit float performance
Yeah, this is why I'd like some solid information about what works and what doesn't - all I have to go on is AMD's product info and docs, and the fact that it kind of looks like it should be supported on macOS.I have my own shader editing tool, and running a very simple test (take a 4 component vector and sin() it ~5000 times), I can compare the results. With a float4 performance is ~25% higher than with packed_half4. There's no performance difference between half4 and packed half4.
